Single-ply replacement: TPO and PVC
Most Houston low-slope roofs end up on TPO or PVC. TPO's reflective surface cuts cooling load through a brutal Gulf Coast summer and its heat-welded seams outperform anything adhesive-based in this humidity. PVC is the answer where grease, chemical exhaust or restaurant kitchen discharge would attack TPO. We specify membrane thickness, insulation R-value and attachment to the deck type and the wind zone, then water test the finished roof before handover.
Restoration instead of replacement — when the numbers work
A silicone restoration can add a decade or two to a serviceable roof for a fraction of a tear-off, and it stays a maintenance expense rather than a capital project. The deciding factor is trapped moisture, which is why we run thermal moisture mapping first. Wet insulation gets cut out and replaced, or the building gets a full replacement — we will tell you which, in writing, before anyone quotes a coating.
NDL warranties and roofer-of-record programs
For institutional owners, the warranty is the asset. No Dollar Limit coverage puts the manufacturer behind both material and labor with no cap on repair cost, but it only issues when the system is installed to spec and inspected. We build to that standard and handle registration. Owners with several Houston buildings typically put us on as roofer of record with scheduled preventative maintenance, which is also what keeps the NDL in force.
Zero business interruption
We never leave a roof open overnight. Sections are torn off and dried in the same day, dock doors and entrances stay usable, staging is set where it will not take customer parking, and the noisy phases are scheduled around your operating hours. On occupied multi-family we add resident notices and building-by-building sequencing so management is not fielding surprise calls.
Leaks, storm damage and diagnostics
Water travels under a membrane before it shows up on a ceiling tile, so we trace leaks to the actual source with video diagnostics and moisture scanning rather than patching the stain. For urgent leaks, our local restoration partner handles the immediate response and any interior water work; P91 handles the diagnosis and the permanent roof repair.
Across Greater Houston and north
We work the full metro and the northern corridor: The Woodlands, Conroe, Spring, Tomball and Magnolia. Have a project to bid? Send it through our RFP intake and we will respond with a scoped proposal.
FAQ
What size commercial roofs does P91 take on in Houston?+
From single-tenant retail pads of a few thousand square feet up to multi-building industrial and multi-family portfolios running several hundred thousand square feet. For larger programs we act as roofer of record and stage the buildings across budget years.
Can the work happen without interrupting our operations?+
Yes. We phase tear-off and dry-in section by section so no area is ever left open, keep dock doors, entrances and parking lanes usable, and schedule the loudest work outside your peak hours. Occupied buildings are the norm for us, not the exception.
What is an NDL warranty and do you provide one?+
A No Dollar Limit warranty is issued by the membrane manufacturer and covers both material and labor for leak repairs with no cap on the repair cost. We install to the manufacturer's NDL specification and handle the inspection and registration so the warranty actually issues.
Should we replace the roof or restore it with a coating?+
It depends on the moisture in the existing assembly. If the insulation is dry and the membrane is intact, a silicone restoration can add 10 to 20 years at a fraction of replacement cost. If moisture is trapped, coating over it only hides the problem — that is why we scan before recommending.
Do you handle insurance and storm damage claims on commercial buildings?+
We document the damage thoroughly with drone imagery, moisture scans and a written scope so your carrier and adjuster have verifiable evidence. We do not negotiate claims on your behalf, and we scope honestly whether or not it is covered.
How quickly can you get on our roof?+
Call (281) 948-2208 and we schedule a site walk, typically within a few business days across Greater Houston, with a written condition report and budget number to follow.
